Hi, I am aware of the CPU usage problem. PoS coins do this when there are many transaction splits. I was able to replicate this issue with Blackcoin, Sling, BTX, and DarkSilk. I am working on a fix.
The unconfirmed rewards is another issue. Are they conflicted?
Thanks for your reply CryptoVote.
Yes I guess they're conflicted. The wallet seems to be confused as it's still many weeks behind yet it's staking and I'm getting constant notifications of incoming stakes but they all remain with ? status. If that's what conflicted is then, yes.
